Typical plot with predicable dialogue.

Start of the drama I already can see that there will be too many disgusting characters
Office male butt
Overbearing mom you can skip all her lines right away

I am not sure how realistic this is but the office male dominating environment with frequent sexist comments as the norm seems excessive?
Overbearing mom w/ too many lines
The ex insulting her age and income status yet comes back to assume his act can be forgiven?
She gets wrongfully terminated and she doesn't fight back
This is all within the first 3 ep and with zero comedic side kicks aka supporting characters.

What's good about this drama?
Actress - she's 40+ looks 30!! She played her character well just that the script was terrible
